Linear regression coefficients for the relationships between PJVF and G′ and G″ with unrestricted flow and with jugular compression, and change in mean G′, G″, and maximal caudal CSF velocity

	R²	P
G′ and PJVF, unrestricted flow	0.136	.330
G′ and PJVF, jugular compression	0.475	.040^{^a}
G″ and PJVF, unrestricted flow	0.151	.301
G″ and PJVF, jugular compression	0.449	.048^{^a}
% Change G′ and % change in max. caudal CSF velocity	0.412	.063
% Change G″ and % change in max. caudal CSF velocity	0.171	.268

Note:—max. indicates maximum.
